Spine:腰椎内固定可致固定节段远端椎间孔及神经根压力升高

2014-11-12 orthowhq 丁香园

脊柱内固定自20世纪70年代描述以来,已广泛用于各种脊柱疾病的治疗,包括退变,创伤,肿瘤和畸形。椎弓根钉系统由后向前贯穿脊柱的三柱,可实现牢固内固定,不像椎板下钢丝和钩只固定后柱。但由于可能的置钉错误,而导致如术后根性症状,假关节和内固定失败。 术中椎弓根钉置钉通常以平片确定,包括正侧位,电视X光机或椎弓根壁的试探。有文献报道,术中拍片有较高的错判率,可误将错误置钉以为正确。尽管X光机可

脊柱内固定自20世纪70年代描述以来,已广泛用于各种脊柱疾病的治疗,包括退变,创伤,肿瘤和畸形。椎弓根钉系统由后向前贯穿脊柱的三柱,可实现牢固内固定,不像椎板下钢丝和钩只固定后柱。但由于可能的置钉错误,而导致如术后根性症状,假关节和内固定失败。

术中椎弓根钉置钉通常以平片确定,包括正侧位,电视X光机或椎弓根壁的试探。有文献报道,术中拍片有较高的错判率,可误将错误置钉以为正确。尽管X光机可用来透视确定位置,但透视过程中手术医生和手术室人员会接触不同程度的射线。以椎弓根探子探触椎弓根壁也不够精确。不恰当的椎弓根螺钉置钉位置可以对椎间孔内的神经根产生影响。

日本饭冢市脊柱损伤中心骨科的学者,进行了探索测量腰椎椎间孔神经根压力的研究,提示腰椎内固定可致固定节段远端椎间孔及神经根压力升高,文章于2014年10月发表在Spine上。

该研究首先报道了自2000年到2012年,710例因腰4退变滑脱行腰4-5减压+后外侧融合的病例中,11例椎弓根钉置钉不当,其中10例患者因腰5椎弓根钉而致腰5神经根痛,1例因腰4椎弓根钉而致腰4神经根痛。所有患者均进行了翻修重新置钉。

该研究共纳入18例因腰4椎体退变滑脱而腰3-5椎管狭窄的病例,平均年龄44.9岁,行腰3-5减压+腰4后外侧融合。术中采用一种微探头导管压力传导器,通过减压的腰3-5椎板,将探头置于腰4-5和腰5-骶1椎间孔内、椎弓根下方、神经根背侧(图1),于腰椎中立位和后伸位两种体位(图2),探测固定前后的压力。

结果显示,腰4-5椎间孔的局部压力,固定前,中立位和过伸位分别为29.74±16.26和51.57±23.18 mmHg;固定后分别为39.13±17.69和41.71±17.94 mmHg。局部压力在固定前,脊柱由中立位至后伸位时,明显升高,而固定后两种体位下,压力变化不大。

腰5-骶1椎间孔的局部压力,固定前,中立位和过伸位分别为26.91±18.16和 54.36±26.67 mmHg;固定后,24.82±17.1和58.46±32.78 mmHg。固定前后,中立位至后伸位时压力明显升高。固定后较固定前,压力明显升高。

肥胖被认为是腰痛的独立危险因素。美国国立卫生研究院对肥胖的分级如下规定:BMI在25-30间为超重,30-40则为肥胖。外科医生认为,肥胖患者手术暴露困难,手术时间较非肥胖患者延长。并且,有研究认为,超重或肥胖患者行选择性脊柱融合的围手术期并发症发生率为36.9%。 目前,肥胖和非肥胖患者行微创或开放脊柱手术的研究有大量报道,然而,没有研究比较超重或肥胖患者行微创或开放椎间孔腰椎融合术的疗效

颈后路椎板成型术为治疗多节段颈椎病广泛认可的手术方法,临床效果确实。但术后上肢瘫,特别是C5神经瘫,为颈后路椎板成型术相对常见的并发症。其原因可能有两个:一是神经根牵拉导致损伤;另一个为缺血和/或再灌注损伤导致的脊髓节段病变。然而,其主要原因尚有争论。 C5神经瘫的发生率报道为4.6%,不同研究中差别较大(0-30%)。因此,很有必要探讨C5神经瘫的危险因素。 中国北京北医三院骨科的学

Spine J:椎间盘脱出时破出物在椎管内移动模式的大样本研究

当椎间盘内容物,包括髓核,软骨终板,骨块,纤维环等,移位超出椎间盘范围,即发生椎间盘突出。突出的椎间盘游离部分可在椎管内沿着边缘,尾端或外侧方向移动。确定已移动的椎间盘破出物对于正确的手术治疗计划很重要,因破出物类似于肿瘤,血肿和脓肿。 MRI,特别是增强扫描,可作为评估移动椎间盘破出物的方法。尽管椎间盘破出物移动很重要,目前为止,文献中尚无深入探讨其移动模式的报道。 伊朗Tabriz大学医学
